The Internet

The Internet is the single most transformative invention in human history, reshaping global communication and commerce. Born from ARPANET in the 1960s and opened to the public in the 1990s, it connected over 5 billion users by 2024, driving 62% of global retail transactions through e-commerce. Outperforming the Printing Press (#3) in speed of adoption, the Internet compressed the knowledge revolution into decades, whereas that earlier invention took centuries to accelerate knowledge sharing. It has transformed industries from publishing (print revenue fell 50% since 2010) to healthcare (telemedicine grew 38x during the pandemic) faster than any prior medium, making it the indispensable backbone of modern life.
